Here is the setup. One laptop, wired/wireless connection. One iPad 2. Zyxel DSL Modem that is also a wired router. NEW Asus RT-N16. Basically I want to create a wireless network using the Asus.

I attempted to reroute the configuration like this: Cable modem -> Switch -> Linksys & Netgear routers where 2 offices would be on one router and a segregated network for the third office.
